Microencapsulation and Fermentation of Lactobacillus acidophilus LA-5 and Bifidobacterium BB-12

Because of poor survival of probiotic bacteria, microencapsulation evolved from the immobilized cell culture technology used in the biotechnological industry.Two probiotic strains, Bifidobacterium (BB-12) and Lactobacillus acidophilus (LA-5) were Outdoor Sling Swivel Chair (set of 2) immobilized in calcium alginate by extrusion method.Encapsulation parameters and efficacy of this method were evaluated.

Growth factors of these two bacteria were also measured by culturing in 10-L fermenter.Growth curves were obtained with respect to optical density and dry biomass weight.Encapsulation yield was over than 60% in each experiment.

Scanning electron microscopy (SEM) of Entrapment of cells in Ear alginate matrix and cross-sections of dried bead were obtained and illustrated.Bifidobacterium have been shown better biotechnological properties.
